杂交水稻抗性育种策略探讨
Discussions on breeding strategies for resistant hybrid rice
摘要
Abstract
This paper discusses about the progress made in breeding efforts for developing rice varieties resistance to various diseases and insect pests such as rice blast, bacterial blight, rice plant hopper, stem borer, etc., and breeding strategies applied for the purpose. The breeding for resistance to rice blast included the exploration of resistant germplasm resources, identification and isolation of resistance genes and their pyramiding, and natural selection of clones from long term disease affected. The utilization of Xa23 gene for breeding rice varieties with resistance to bacterial blight disease and utilization of newly discovered genes, viz., bphl4, bphl5 and bphl8, etc., for plant hopper resistance of Guangxi, have been proposed. This paper also summarizes the efforts made in breeding stem borer resistant varieties using transgenics and the use of molecular markers for identification of disease and pest resistance in breeding procedure.关键词
